Need help for multi-db installation

Hi everybody!

I've got some problems with the plugin multi-db installation since two days, even if I've followed all the instructions given in this url :

https://premium.wpmudev.org/project/multi-db/installation/

Still, there were some parts seem to me a little bit fuzzy. However, I've finished the plugin's configuration : database creation and creation of a user for all database.

My problem is when I go to this url :
http://www.mysite.com/wp-content/scripts/move_blogs.php
the site is inaccessible and my browser says to me : this web page presents a bug of redirection and turns up on :
http://www.misite.com/wp-singup.php?new=misite.com

So I need a help to resolv this problem

Below my configuration files

Number of database : 4096

  1. Tested on PHP 5 & MySQL 5
  2. Make sure all of your new db's exist (green text next to table name in db column below)
  3. In the status section, each table should show <i>not in new db (unless you've already run this script)</i>
  4. To start the copy process click here
  5. Be patient, depending on how many blogs you have, this could take a while
  6. Once completed, refresh this page by clicking here
  7. Check to make sure that in the status section all tables say <i>table in new db</i>
  8. Rejoice, I probably just saved you hours of your life!
  9. If this didn't work, don't blame me. Sometimes life is just like that..
